node based or cell centered Ts values

acboge

Hi, I am solving a conjugate heat transfer problem on a solid wall facing a fluid region on one side. Therefore the Fluent creates a shadow wall on the top of the solid wall. My problem is, after the solution when I plot the node based static temperature values and the node based total temperature values on the same solid wall, they are quite different. As the velocity on the wall is zero, I expect them to be close. On the other hand, if I look at the cell center values of the total and static temperatures on the wall, they are quite close and different from the node based values. Does any one encounter such a problem in a heat transfer calculation? Any suggestions ?
